The Cassini plasma spectrometer instrument (CAPS) aboard NASA's Cassini spacecraft was turned off between Friday, June 1 and Saturday, June 2, when a circuit breaker tripped off after the instrument experienced some unexpected voltage shifts.

NASA unveiled a new atlas and catalog of the entire infrared sky today showing more than a half billion stars, galaxies and other objects captured by the Wide-field Infrared Survey Explorer (WISE) mission.

NASA's Cassini mission to Saturn, managed by the Jet Propulsion Laboratory, Pasadena, Calif., has received the top group honor from the Smithsonian's National Air and Space Museum - the Trophy for Current Achievement. Representatives for Cassini will receive the trophy on March 21 at a black-tie dinner in Washington, D.C.
